The boiled or steamed root corm of Colocasia esculenta. Starchy, creamy, slightly sticky, with a mildly sweet, nutty flavor. One of the lowest glycemic starchy roots available — GI of 53 versus 78 for white potato. Very high in potassium and resistant starch. The corm (root ball) is distinct from taro leaves (which have a separate nutritional profile).
Available fresh and frozen at Asian, Caribbean, African, and Latin grocery stores. Widely available in US cities. The taro bubble tea and taro chips trend has made taro increasingly available at mainstream grocery stores.
Taro root has among the lowest glycemic indices of commonly eaten starchy root vegetables (GI ~53 vs. white potato ~78). The resistant starch content — which increases significantly when taro is cooked and cooled — provides robust prebiotic fermentation substrate for gut Lactobacillus and Bifidobacterium. A 2016 study in Food Chemistry documented taro polysaccharides stimulating gut beneficial bacteria while inhibiting pathogenic species. The 4.3g fiber per 100g exceeds potato, cassava, and most root vegetables. Potassium at 591mg/100g supports blood pressure reduction at population scale — particularly significant given that Black Americans have the highest hypertension prevalence of any demographic in the United States.
Peel, cube, and boil in salted water 20-25 minutes until fully tender (must be completely cooked — raw taro contains calcium oxalate). Steam or roast whole taro at 400°F for 45 minutes. Can be mashed, pureed for poi, or sliced and pan-fried in coconut oil. Cool cooked taro before eating to maximize resistant starch.
